text: We investigate the ground-state energy of a one-dimensional Fermi gas with
two bosonic impurities. We consider spinless fermions with no fermion-fermion
interactions. The fermion-impurity and impurity-impurity interactions are modeled
with Dirac delta functions. First, we study the case where impurity and fermion
have equal masses, and the impurity-impurity two-body interaction is identical
to the fermion-impurity interaction, such that the system is solvable with the
Bethe ansatz. For attractive interactions, we find that the energy of the impurity-impurity
subsystem is below the energy of the bound state that exists without the Fermi
gas. We interpret this as a manifestation of attractive boson-boson interactions
induced by the fermionic medium, and refer to the impurity-impurity subsystem
as an in-medium bound state. For repulsive interactions, we find no in-medium
bound states. Second, we construct an effective model to describe these interactions,
and compare its predictions to the exact solution. We use this effective model
to study nonintegrable systems with unequal masses and/or potentials. We discuss
parameter regimes for which impurity-impurity attraction induced by the Fermi
gas can lead to the formation of in-medium bound states made of bosons that repel
each other in the absence of the Fermi gas.

text: Motivated by recent experimental observations of coherent many-body revivals
in a constrained Rydbergatom chain, we construct a weak quasilocal deformation
of the Rydberg-blockaded Hamiltonian, whichmakes the revivals virtually perfect.
Our analysis suggests the existence of an underlying nonintegrableHamiltonian
which supports an emergent SU(2)-spin dynamics within a small subspace of the
many-bodyHilbert space. We show that such perfect dynamics necessitates the existence
of atypical, nonergodicenergy eigenstates—quantum many-body scars. Furthermore,
using these insights, we construct a toymodel that hosts exact quantum many-body
scars, providing an intuitive explanation of their origin. Ourresults offer specific
routes to enhancing coherent many-body revivals and provide a step towardestablishing
the stability of quantum many-body scars in the thermodynamic limit.

text: In 1915, Einstein and de Haas and Barnett demonstrated that changing the magnetization
of a magnetic material results in mechanical rotation and vice versa. At the microscopic
level, this effect governs the transfer between electron spin and orbital angular
momentum, and lattice degrees of freedom, understanding which is key for molecular
magnets, nano-magneto-mechanics, spintronics, and ultrafast magnetism. Until now,
the timescales of electron-to-lattice angular momentum transfer remain unclear,
since modeling this process on a microscopic level requires the addition of an
infinite amount of quantum angular momenta. We show that this problem can be solved
by reformulating it in terms of the recently discovered angulon quasiparticles,
which results in a rotationally invariant quantum many-body theory. In particular,
we demonstrate that nonperturbative effects take place even if the electron-phonon
coupling is weak and give rise to angular momentum transfer on femtosecond timescales.

text: Cells need to reliably sense external ligand concentrations to achieve various
biological functions such as chemotaxis or signaling. The molecular recognition
of ligands by surface receptors is degenerate in many systems, leading to crosstalk
between ligand-receptor pairs. Crosstalk is often thought of as a deviation from
optimal specific recognition, as the binding of noncognate ligands can interfere
with the detection of the receptor's cognate ligand, possibly leading to a false
triggering of a downstream signaling pathway. Here we quantify the optimal precision
of sensing the concentrations of multiple ligands by a collection of promiscuous
receptors. We demonstrate that crosstalk can improve precision in concentration
sensing and discrimination tasks. To achieve superior precision, the additional
information about ligand concentrations contained in short binding events of the
noncognate ligand should be exploited. We present a proofreading scheme to realize
an approximate estimation of multiple ligand concentrations that reaches a precision
close to the derived optimal bounds. Our results help rationalize the observed
ubiquity of receptor crosstalk in molecular sensing.
